The other day I was passing through the Union Square subway station.  Suddenly, realistic “frames” with pictures of decadent Italian meals graced the walls.  I knew they weren’t real, but the quality of the images proved pretty realistic.  “What is the about?” I asked myself.  A few feet away my questions were answered, Buitoni, an company that sells prepackaged Italian fare.  I know pictures of food can lie, but it looked good and hey, beats the normal dirty tile wall I usually see when passing through.
